Estimating the term…
A method for producing a catalyst for a fuel cell is provided which is capable of improving output characteristics of the fuel cell. Metal fine particles making up the catalyst for the fuel cell to be used as a fuel electrode and air electrode are formed by reducing platinum salt with molybdenum carbonyl. The catalyst for the fuel cell is formed by supporting platinum-molybdenum fine particles on carbon particles. By employing this reducing method, platinum-molybdenum fine particles being small in size and high in dispersibility can be obtained, making the catalyst for the fuel cell highly active. By constructing the fuel and air electrodes using the catalyst for the fuel cell, high outputs from the fuel cell are made possible.
A method for producing a catalyst, in which metal fine particles are supported on a supporter, for a fuel cell to be used as an electrode for said fuel cell, comprising the process of:
A method for producing a fuel cell using, as its electrode, a catalyst obtained by supporting metal fine particles on a supporter, comprising the process of:
A catalyst for a fuel cell obtained by supporting metal fine particles on a supporter to be used as an electrode for said fuel cell, comprising:
A fuel cell using, as an electrode, a catalyst in which metal fine particles are supported on a supporter, wherein said catalyst formed by reducing platinum salt with metal carbonyl of a metal being different from said platinum and obtained by supporting metal fine particles containing said platinum and said metal on supporter particles to be used as a supporter is used as said electrode.
